Welcome

Welcome to the web site of the Physics Instructional Resource Team (PIRT) at Arizona State University. The PIRT is pleased to present you many ways in which we accomplish our mission “Focused on Excellence” in Physics Education. We are inviting you to explore our lecture demonstration and media collection catalogs through this website as well as information and web resources on physics pedagogy. If you would like to order the demonstration for the lecture, please, log in. It is our intention to expand this web site by adding a catalog of our laboratory experiment collection. Get to know us and let us know how we can help.

To investigate the attenuation of gamma radiation by lead and the attenuation of beta radiation by polyethylene. To find the mass attenuation constants for both materials. To observe the penetrating properties of alpha radiation.
